AI Technical Summary

Technical Problem

The hydraulic ceramic plunger mud pump suffers from unstable oil pressure during use, making effective pressure compensation impossible and affecting its service life.

Method used

A pressure compensation device including a connecting pipe, an oil reservoir, and a one-way oil inlet assembly is designed. When the oil pressure is too high, the solenoid valve is opened by the pressure gauge, and the oil enters the connecting pipe and is temporarily stored in the oil reservoir. The sliding of the support sleeve is adjusted by the adjustment assembly to control the opening and closing of the sealing plate, so as to achieve adaptive compensation of oil pressure.

Benefits of technology

It effectively alleviated oil pressure fluctuations in the oil pipeline, achieved oil pressure stability, and extended the service life of the equipment.

Abstract

This utility model discloses a pressure compensation device for a hydraulic ceramic plunger mud pump, relating to the field of hydraulic pressure compensation technology. Its key technical features include an oil pump, oil pipe, connecting pipe, oil reservoir, and a one-way oil inlet assembly. The one-way oil inlet assembly includes a fixed sleeve fixedly installed inside the oil reservoir. A support sleeve is slidably installed inside the fixed sleeve. A support rod is slidably installed at one end of the support sleeve, and a closing plate is fixedly connected to one end of the support rod. A spring is installed inside the support sleeve. An adjusting component for adjusting the support sleeve is provided at the end of the oil reservoir away from the connecting pipe. The technical effect is that by setting up the connecting pipe, oil reservoir, and one-way oil inlet assembly, when the oil pressure in the oil pipeline is too high, some oil will enter the oil reservoir for temporary storage, thereby relieving the oil pressure in the oil pipeline. When the oil pressure decreases, the oil in the oil reservoir is discharged, compensating for the oil pressure.
